According to Us Weekly, Bobby Brown‘s sister Leolah Brown claims that she knows how Whitney Houston got the cocaine that was found in her system the day she died — and her finger is pointed right at Ray J.

But Ray J‘s rep tells Us Weekly, that Leolah’s remarks on CNN’s Headline News with Dr. Drew Thursday, where she accuses Brandy Norwood‘s younger brother as being a “runnerboy,” are “rife with false statements.”

“Even though Leolah Brown was nowhere near the Beverly Hilton Hotel on the day Whitney Houston died, Ms. Brown falsely claimed that Ray J was at the hotel and contributed to Whitney Houston’s death,” Ray J’s rep says. “Even the most minimal inquiry with anyone actually in contact with Whitney would reveal that Leolah Brown had been out of contact with Whitney for more than a year.”

On Thursday, the L.A. Coroner’s office released the results from Houston’s autopsy that ruled her main cause of death as an accidental drowning.

The legendary singer, who was found submerged under water inside a bathtub in her Beverly Hills hotel room February 11, also had traces of cocaine in her system and was suffering from effects of heart disease at the time of her death. The report rules out foul play and trauma.
